The Sense & Grow Dual Liquid Timer is a fun device that is full of brightly coloured liquid. One side has blue and the other pink. In the middle, there is a little spinning wheel on one side and a flower on the other. When the Dual Liquid Timer is turned upside down and back again, the liquid will flow. This is a great way to help a child learn the basic concept of time. It also helps their fine motor skills as they twist and turn this to make the liquid go in all kinds of crazy paths.
